The LED display shows the carbon dioxide concentration and time-weighted average (TWA) in real time while a series of LEDs instantly shows the user when CO2 levels are dangerous. In addition, a 2kHz alarm will sound until the user presses a button.

A built-in data logger also makes it the perfect choice for monitoring CO2 in a number of different applications and environments. And the sensor’s gold-plated infra-red waveguide and diffusion membrane filter provides reliability, accuracy and long-term stability.
